I am currently running Providence 1.7.5 and Pawtucket on a website hosted by SiteGround, having recently moved from hosting by UK2. (The problem described below existed on the old host and continues with the new host.)
From time to time large folders/files are created. The sizes are typically around 50 – 55 MB. I have no idea why they are created, there does not seem to be a fixed pattern. Several days can pass without any new ones, however on 3rd December multiple files were created until the available disk space was filled and the site crashed. After deleting the files the functionality was restored.
There are two types of file those designated phpxltmpxxxxxx which are saved in the /Pawtucket main folder and those designated phppttmpxxxxx which are saved in the/tmp folder on the server home folder. Both types seem to contain zipped image files, in addition the phppttmpxxxxxx type contains files of slides.
Please can someone explain what is happening and how I can prevent these files being saved permanently.
